9.2.4 Numeric Mode

To simplify command/response interactions with automated systems where it may be more problematic to generate and parse string content, the DCE supports a numeric mode. In this mode commands and responses can be represented in number strings of fixed format.

Each command, response and AEC has a two part ID: a module ID and a command/AEC ID. These two numbers are combined in the form:

MM:NN

Where MM is the hexadecimal representation of the module ID and NN is the hexadecimal representation of the command/AEC ID.

Commands can thus be issued as:

AT+MM.NN=

Responses and AECs will be formatted as:

+MM.NN:

While in numeric mode the DCE will still accept full command name strings as well as numeric format, but all responses and AECs will be in just numeric mode.

Numeric mode does not apply to the success or error responses returned by the DCE. If the DTE also wishes to use simplified formatting for these responses the command ATV can be used with either a parameter of 0 or 1 to replace ‘OK’ and ‘ERROR’ with ‘0’ and ‘1’.
